Dinosaur Noise - Ghost Train - GTA Online

This is a video I recording that has a very strange sound on it, and also by the sounds of it a ghost train as I hear the noise of a train..but nothing is there. I would appreciate any likes / comments / subscribers....or even dislikes just so I know what I could do to make things better. (just a quick note, I have made this new account so the original time I have posted this video is on my other account which is sirsnoobles)
